We used GSA for an event we had in London. They handled lead generation and telemarketing for the event. They were very thorough and touched base with us every step of the way to make sure the campaign was successful. They are professional and prompt and kept us up to date with the campaign and the milestones as we progressed closer to the event. I highly recommend if you need a telemarketing & B2B lead generation services you should reach out to GSA and talk to Jonathan and Monica
We engaged GSA to support our event delegate telemarketing campaign, and the results were excellent. Their team was professional, responsive and highly organised — they quickly understood our goals and delivered quality leads that helped boost delegate registration. Communication throughout the process was clear and efficient. We’re very pleased with the service and would happily work with them again.
